Neulasta (pegfilgrastim) is a colony-stimulating factor (blood cell booster) that's similar to a protein your body makes naturally. It works to make a type of white blood cell called neutrophils grow faster, which help your body fight infection.

Risks and Warnings for Neulasta (pegfilgrastim)

Neulasta (pegfilgrastim) has been reported to cause hypersensitivity reactions (severe rash, trouble breathing), and angioedema (life-threatening condition with swelling with or without hives).
